Subject: [PATCH 0/2] mm/page_alloc: fixes for free_pages_nolock() on RT/UP
Date: Wed, 15 Jul 2026 09:03:57 +0000 [thread overview]
Message-ID: <20260715-alloc-nolock-fixes-v1-0-fadc49952dda@google.com> (raw)
First patch was originally part of a different series but Andrew asked
for it to be separate:
https://lore.kernel.org/all/20260710170311.e22bfd21c658e8357ceddeec@linux-foundation.org/
Pre-existing bugs found by Sashiko during review of this other series:
https://lore.kernel.org/all/20260703-alloc-trylock-v5-0-c87b714e19d3@google.com/
I have not reproduced these bugs, and I suspect there is no real-world
user that is affected by them.
